Subject: [PATCH] ts_31_102: Fix decode_select_response() for DF.5GS

In Change-Id I848a766e6d00be497c7db905475e0681cce197ac we added a CardDF
instance for DF_5GS.  That DF should not have provided a
decode_select_response() method, and instead fall back to that of the
base class, which calls the method of the parent directory (ADF_USIM).

The difference is illustrated below

pySIM-shell (MF/ADF.USIM/EF.IMSI)> select DF.5GS
"622e8202782183025fc0a509800171830400018d088a01058c056611111111c60f90017083010183018183010a83010b"

vs. (with this patch):

pySIM-shell (MF/ADF.USIM)> select DF.5GS
{
    "file_descriptor": {
        "shareable": true,
        "file_type": "df",
        "structure": "no_info_given"
    },
    "file_identifier": "5FC0",
    "proprietary_info": {
        "uicc_characteristics": "71",
        "available_memory": 101640
    },
    "life_cycle_status_int": "operational_activated",
    "security_attrib_compact": "6611111111",
    "pin_status_template_do": "90017083010183018183010A83010B"
}
